HEADLIGHT-LENS.

To all whomit may concern: Be it known that I, Loms'DUFnK, a c tizen of the Czechoslovakia Republic, residing at Rainier in the county of Columbia and State of (lregon, have invented a new and useful Headlight-Lens, of which the.-

like, wherein the upwardly extending rays of light will be dimmed and of a difi'erent and more subdued color than those extending downwardly; at the same time, the headlight in connection with the lens effectively projecting light over the road of travel. l attain these objectsby the device illustrated in the accompanying drawing, in which-- Figure 1 is a front elevationof said lens. Fig. 2 is a vertical sectional view of the same. J

The lens, when in operative position, is slightly concave on its inner surface, its outer surface having a series of curved ridges 1, located transversely with relation to the body of the lens and extending nearly to the edge thereof,-2; said ridges also extend outwardly and incline downwardly, as shown in Fig. 2. The body of thelens and said ridges comprise an integral structure made of uncolored transparent glass, being the material out of which lenses or: cover glasses for vehicle headlights are ordinarily made. During the course of manufacture, a layer of different colored glass is applied to the top surface of each ridge, producing as a completed lens, one wherein each. transversely extending ridge has as its upper surface, and as an integral part thereof, a layer or lamina of different colored glass designated by the Fig. 4.. While other colors can be used to advantage, I find a green color for said top surfaces to be particularly desirable as it is a color very easy Specification of Letters Patent.

on the eyes. The lens provided with said ridges, in connection with the headlight of an automobile, will permit white rays of light to illuminate the roadway. The green colored glass with which the upper surfaces of the ridges a'rev provided dim and color the upwardly extending rays of light so that the driver can more easily see the roadway, and the light is less blinding on those who may be approaching. The gist of my invention resides in the fact that I provide in a headlight lens or cover glass, aplurality of transversely extending ridges, each ridge carrying as its upper surface, and as an integral part of the ridge and body, a thin layer ofdiflerent colored glass, preferably green, the whole lens being of transparent 1 glass. It is obvious to one skilled in the art that the construction of the body of the lensor the form of the ridges can be varied without departing from the spirit of my invention. J

Having thus described my invention, I claim:;

1. A headlight lens, comprising a body made of a sing e piece of uncolored glass, its outer'surface having a plurality of ridges integral therewith curved substantially across the same, and extending outwardly and downwardly in spaced parallel relation,

the top surfaces of said ridges having superimposed thereon integral portions of colored transparent glass adapted to color and sub-.-

due the brilliancy of ascending rays of light.

2. A headlight lens, comprising a body made of a single piece of uncolored glass, its outer surface having a plurality of ridges integral therewith located substantially across.

the same, and extending outwardly and downwardly in spaced parallel relation, the

top surfaces of said ridges having superimposed thereon integral portions of colored transparent glass adapted to color and subdue the brilliancy of ascending rays of light.
